Frank,
I think you are correct, I just found their web site, do not know whether it is Audax driver though, it sound very nice not broken in yet. Driven by a pair of very strange big tube mono amps, with five chrome plated circular covers, Mastersound something.

You don't really need crossover in a woofer (if properly chosen), and that's what I'm doing with my Triangle mini-monitors. But the cap is almost necessary in a tweeter network, if only for protection against excessive power levels.
